PAD DIAGRAM: The outputs of the VSC7997 and VSC7998 are linear for inputs up to 250mAp-p and 1000mAp-p respectively. For higher inputs, the output limits at typically 1000mV differential, increasing the dynamic range of the system by reducing the possibility of exceeding the input voltage range of the limiting amplifier or clock and data recovery circuit. BENEFITS: High Gain with Low Power Direct Connection to a Demux without a Post Amplifier
